One of the fastest elevators in the world is found in the Taipei 101 building. It ascends at 16.83 m/s and rises 382.2 m. Each elevator has a maximum load capacity of 1600 kg. What power P is required to raise a load of 1260 kg from the lowest level to the top floor? P = W Jack and Jill, whose masses are identical, go up a 300-m hill to fetch a pail of water. Jack climbs a sheer rock face to reach the top, while Jill follows a meandering path 915 m long. What is the magnitude of the difference between the work Jack does against gravity and the work Jill does against gravity to get to the top? difference: J A 1270-kg car moves at 24.0 m/s. How much work Wnet must be done on the car to increase its speed to 35.0 m/s? W net = J
